Motor is an eBay 175 top end using a delloto sh1/20 carb with foam type filter and a scootopia 42 ancilloti .

Choke and idle seems ok as starts and idles ...I have put a 122 main in ...any suggestions on main or Is it in the ballpark.

Cheers Simon

A tv175 with sh1/20 has 108 with airbox and standard exhaust, so I'd say you're in the right ball park for the main, but probably a bit rich.
